SPECIFICATION forming part of Letters Patent No. 782,635, dated February 14, 1905.

Application filed October 28, 1903. Serial No. 178,951.

T0 at whom it may concern:

Be it known that I, GEORGE W. WINTERS, a citizen of the United States, residing at Fitzgerald, in the county of Woodward and Territory of Oklahoma, have invented new and useful Improvements in Type-Writers, of which the following is a specification.

My invention relates to improvements in type-writing machines; and the object is to provide a hand-machine which is of light weight and small dimensions and which possesses all the requisites of certainty and efficiency in manipulation and mechanical action.

With these objects in view the invention embodies the construction of parts and their aggroupmentin operative combination, as will be hereinafter fully specified and the novelty claimed particularly pointed out and distinctly asserted.

I have fully and clearly illustrated the invention in the annexed drawings, to be taken as a part of this specification.

Reference being had to the drawings, Figure 1 is a top plan view of the complete machine, showing the hand-grasps by which the machine is actuated, the index-plate, the typewheel, the type-bar, and the paper carriage and rollers. Fig. 2 is a plan view similar to Fig. 1, with the type-wheel and index-plate removed, showing the actuating rack-bar. Fig. 3 is a bottom plan view showing the roller on which the paper may be rolled and thence fed to the feed-rollers. Fig. 4 is an end view of the machine. Fig. 5 is a transverse section of the parts centrally through the type-wheel. Fig; 6 is a detail perspective view of the carriage-feeding mechanism and the type-bar-actuating devices. Fig. 6 is a detail sectionalview of the carriage-feeding mechanism. Fig. 7 is a detail section of a portion of thetype-wheel, showing the arrangement of the types therein. Fig. 8 is a plan view of the type-wheel with the types disposed therein and the return-springscom nected thereto. Fig. 9 is'a bottom face view of a portion of the frame-plate and of the carriage, showing the tube secured to the bottom face of the plate and the carriage-bar arranged therein.

In the drawings similar parts appearing in the several illustrations are designated by similar reference notations.

A designates a rectangular plate of such area as may suit it to the purpose intended and on which the members or elements of the machine are secured and carried. I'intend generally to make this plate eight inches long and one inch wide, but of course do not desire to be limited to these precise dimensions. To the righthand end of the plate A is mounted an index-plate 1, made of a half-circular plate and whereon are placed in radial arrangement the letters of the alphabet and such other essential characters as may be selected for convenience in machines of this character, substantially as seen in Fig. 1 of the drawings. On the plate A, at the center of the circle prescribed by the curve of the index-plate, is journaled a pinion 2, which carries a hand or pointer 3, designed to indicate the letters or characters intended to be produced on the paper. The pointer 3 at its outer end portion rides over and engages in notches made in a curved edge plate 3, the' notches being coincident or in alinement with the letters and characters on the plate 1, so that the pointer will stop directly over the desired character or letter.

4 5 constitute a U-shaped hand-grasp conwith a reciprocable bar 9, formed with a rack 10, which engages with the pinion 2. The bar 9 slides in keepers 11, as seen in Figs. 1

and 2 of the drawings, and is positioned to suit its connections at its outer end, as will be hereinafter stated. In the plate A, at the left-hand end portion, is journaled a pinion 1 2, a duplicate of the pinion 2. The pinion 12 is engaged by a rack 13, formed on the bar 9, and v consists of a circular plate of the requisite diameter and thickness and is provided with the required number of vertical type slots orholes 15, radially arranged and located adjacent to its circumferential edge, and in these typeslots are slidably positioned the types 16, which after depression by the type bar, as hereinafter specified, are raised to normal position by spring arms or rods 17, having their inner ends secured to points on the type-wheel and their outer ends secured to the types, substantially as shown in the drawings. The type-wheel for convenience is covered with a disk 14, substantially as seen in the drawings. index-hand is turned through the compression of the hand-grasp 4 5 and rotation of the pinion 2 to indicate the required character the bar 9 is moved, 'so that the rack 13 rotates the pinion 12, which turns the type-wheel synchronously with the index-arm and brings the required type into position to be in the path of the type-hammer.

On the plate A is journaled a suitable rockshaft 18, from which projects a pin 19, and at a proper point on the rock-shaft 18 is arranged the stem 21 of the type-hammer. The type-' hammer consists of the stem 21, an extension 22 at right angles to the stem and on the diametrical line of the type-wheel, asshown in Figs. 1 and 4 of the drawings, and at the free end of the part 22 the hammer-piece is directed downwardly, as at 23, the end impending directly over the type to be struck. Any suitable means, such as a spring 21, may be connected with the stem 21 in order normally to hold the hammer in elevated position.

24 25 designate the U-shaped hand-grasp for the left hand of the operator, consisting of two cylindrical members united at their outer ends by a bowed spring 26. The member 24 of the hand-grasp is pivotally connected to the plate A by a lug 27, and the member 25 is left free and is provided with an extension 28, which contactswith the stud or finger 19 and actuates the rock-shaft to throw the type-hammer into contact with the types.

29 designates the inking-ribbon, mounted on spools 30, projecting laterally from and carried by the plate A, substantially as seen in the drawings.

B designates the carriage or sliding frame, which consists of a suitable rectangular frame of the same length as the plate A. The carriage-frame is made up of end pieces 31 32, side bars 33 34, intermediate piece 35, constituting the platen-bar, and a round carriagebar 36. The carriage-bar 36 isslidingly disposed in a tube 37, fixed at the proper position on-the rear face of the plate A, as indicated in the drawings. In the space between the bars 34 and 35 is journaled the paper-feed roller 38, the paper being held thereto by short rollers 39 40, journaled in suitable uprights 41, the paper-roller having its journals extended, as at 42, and provided with thumbpieces 43, by which the roller is turned and It will now be seen that when the the paper drawn between the rollers, and the line-spacing thus effected as may be desired. A small roller 44 may be mounted on an arm 45, adjustably carried on the bar 34 of the carriage, the purpose being to provide means to hold one end of envelops when addressing them. i To the rear face of the carriage may be secured supports 46, wherein is journaled aroller 47. on which may be arranged a roll of paper 48, which may be led through the feed-rollers and the writing impressed thereon. Single or separate sheets may be used instead of the, roll. The paper 48 is fed from the front up over the platen-bar 35, thence over the roller 38, and under the end rollers 39. The bar 33 of the carriage is formed with a ratchet 49, having teeth each with a straight edge and an inclined edge, said teeth being engaged by a pawl 50, which is pivoted to the lower end of a rockingarm 0r lever 51, pivotally mounted in a slot in the plate A, with its upper end in the path of the extension 28 of the hand-grasp 24 25. A spring 51', attached to the lower end of the lever 51 and to the plate A, serves to retract the pawl 50 each time it is actuated by the extension 28 of the hand-grasp 2425. An auxiliary pawl 50', pivoted on the plate A, engages the teeth of the rack and prevents backward movement of the carriage when the pawl 50 is retracted preparatory to advancing the carriage. To release the pawls 50 and 51, so that the carriage may be drawn back, a finger 53 is pivotally secured to the plate A, with its inner portion extending under the pawls and its outer portion extending under a sliding rod 54, which has its end .curved, as shown, so that when the rod is slid to the right the curved part will ride on and tilt the finger 53 and lift the pawls from engagement with the rack 49,'and the carriage may then be pushed back manually.

, If desired, a suitable spring or elastic band 54 (see Figs. 3 and 9) may be employed to effect the return movement of the carriage, it

being understood that the action of the same ranged over the platen-bar, thence over the main feed-roller, and under the short end roll- .ers mounted at the end of the main roller.

pinion 12 and coinciden'tly turns the typewheel to stand at the point to bring the selected type directly into the path of the typehammer. The operator then compresses the left-hand hand-grasp, the extension of which strikes the pin 19 of the rock-shaft and turns the shaft, so as to cause the hammer to strike the type and make its impression on the paper. On the release of the right-hand grasp the index is returned to initial point,and with it the type-wheel. The left hand grasp is then released and the extension 28 thereof springs back against and encounters the rockarm 51, thereby shoving the pawl 50 forward and moving the carriage forward one notch or the distance requisite for the next impression, the spring 51 serving to retractthe pawl 50 each time it is actuated. It will be understood that the auxiliary pawl 50' rides over the rack 49 as the pawl 50 advances the carriage in a step-by-step manner. Furthermore, it will be understood that said auxiliary pawl 50 prevents the spring 54 from drawing the carriage backward when the pawl 50 is retracted. The next movement of the right-hand grasp can then be made and the same steps above stated be repeated, and so on until the words of that line are completed.-

When by means of one of the thumb-pieces 43 the paper is turned to position for the'next line, the carriage maythen be returned to the initial point or stopped-at such-point, as may be desired.

It will be perceived that the hand-grasps being pivotally connected to the frame may be turned back on their pivots and lie upon or parallel with the frame-plate of the machine when not in use and the whole machine thus be arranged to be carried in the pocket of a garment.

It will be understood that the feeding movements of the carriage take place from right to left, and in effecting such movements the pawl 50 successively engages with the straight edges of the teeth of the ratchet 49, whereas the pawl successively glides over the inclined edges of said teeth on its return movements, each of these edges serving to lift the pawl to cause it to drop behind the next succeeding straight edge, all as will be apparent.

Having thus fully described the invention, what I claim as new is 1. In a type-writing machine, an indexplate, a rotatable pointer to sweep said plate, a rotatable type-wheel, types slidably disposed therein, a hand-grasp, means actuated by the hand-grasp to operate the pointer and typewheel in unison, and means to depress said type in the type-wheel, said hand-grasp comprising a stationary leg and a movable'leg and a spring connecting the two.
